Newly discovered brain response to obesity drug may inform future treatments
The FDA-approved drug liraglutide has been shown to help obese patients lose weight by suppressing their appetite. However, where and how the drug acts in the brain was not fully understood, until now. A new preclinical study shows how liraglutide crosses the brain's blood barrier to engage with a region of the brainstem known as the nucleus tractus solitarius, which is responsible for balancing food intake and energy expenditure.

Omega-3 fats do not protect against cancer
Omega-3 fats do not protect against cancer -- according to new University of East Anglia research. Increased consumption of omega-3 fats is widely promoted globally because of a common belief that it will protect against, or even reverse, diseases such as cancer, heart attacks and stroke. But two systematic reviews find that omega-3 supplements may slightly reduce coronary heart disease mortality and events, but slightly increase risk of prostate cancer. Both beneficial and harmful effects are small.
